T0 ctZZ whom it 711,003/ concern:

Be it known that I, WILHELM BACHNER, a citizen of the German Empire,residing at Stuttgart, in the Kingdom -of Wurtemberg, Germany, haveinvented certain new and useful Improvements in Apparatus for Coolingand Dispensing Beer or other Liquids; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to apparatus for cooling and dispensing beer andother liquids; and it consists, substantially, in such features ofimprovement as will hereinafter be more particularly described.

rIhe invention has for its object to provide a cooling and deliveringapparatus for beer and it comprises, among other features, an icechestor refrigerator having a uniform and continuous air circulation.

The apparatus is constructed in front With a part formed like asideboard or buffet, in which a beer containing or cooling tank orvessel is located, which is cooled externally by the cold air of theice-chest or refrigerator and the contents of which are cooledinternallyby a separate pipe having ice-Water constantly passing throughit.l The beer-cooling vessel may be connected With a beer-Cask locatedoutside the refrigerator and the contents of the cask transferred tothesaid vessel by means of an air-pump or, as shown, for instance, in theaccompanying drawings, by means of carbonio-acid pressure. A separatearrangement is also employed by means of which, in case. of overfilling,any loss of carbonic acid occasioned by the frothing up of thebeer isavoided, since the air escaping from the refrigerator is under a certainpres-v sure, so that the beer enters quietly. VThe beer is delivered bymeans of one or more taps directly to the sideboard or buffet-shelf ofthe ice-chest refrigerator, a thermometer" arranged behind the tapsallowing of the temperatureof the said beer being directly ascertained.The cooling tank or vessel communicates with a carbonio-acid container,so that the beer is constantly under pressure.

In the accompanying drawings an ice-chest or refrigerator withcontinuous air circulation and a beer-cooler included therein, togetherwith an arrangement for running the beer in and discharging saine, isshown, and in whi`ch Figure l is a side elevation, partly in verticalsection; Fig. 2, a vertical transverse section of same, and Fig. 3 avertical front elevation in part section; Fig. 4.-, a cross-sectiononthe line y y of Fig. 2; Fig. 5, a cross-section on the line :n of Fig.2. Figs. 6, 7, and

`8 are lvertical sections, on anenlarged scale, y of the Abeer-coolerand its appurtenances, the

beer-inlet device K, and thebeer-outlet device M, bymeans of YWhichlatter the aireout let when the cooling vessel is filled is so regulatedthat no frothingof the beer takes place. and other effervescent orfoaming beverages;

The refrigerator or ice-chest A has, preferably, the shape' of abuffet-counter or sideboard, an ice-container B, closed all around,

being inserted in the rear higher part of said buffet, Whichice-container is closed at top by means of alid W and has a grating b2,beneath Which it develops into a funnel-shaped fpart B with a tubularnozzle b', in which lati ter a throttle-valve b3 is arranged, thespindle of which is carried to the outside through the Wall of theice-chest or refrigerator and carries a handle Z131, by which thethrottle-'valve may be openedor closed, Figs. I and 5. A tubular pieceb4, having lateral perforations, is removably fastened, preferably bymeans of a bayonet-joint, onto the nozzle b. Holes h are also formed'inthe sides of the upper part of the ice holder or containerB, so that thecold air can only escape through the holes in h4 and the Warm air canonly enter through the holes b lof the otherwise quite-closedicecontainer B. A const-ant active air circulation is thus establishedin the ice-chest.

B2 is a perforated tube extending centrally of the ice receptacle orcontainer B and is for the purpose of permitting free circulation ofair, which otherwise might beimpeded by the clogging or close packing ofthe ice.

A smaller vessel C', having perforations in the sides and standing in asecond somewhatlarger vessel C,- for receiving or catching the Waterproduced by the melting of the ice, is

IOO

located under the tubular nozzle lr. Dirt and the like accumulates onthe floor of the vessel C by settling, and as this vessel is onlyloosely inserted in the vessel C the same may be readily lifted out andthe sediment or dirt resulting from impure ice and the like may beconveniently emptied without dirtying the water in the vessel C. Thewater formed by the melting of the ice is conveyed from the vessel C bya pipe c into a cup E, situated above the beer containing and coolingvessel H,fro1n whence it passes, by means of a pipe e, through thecooling vessel H into the lower part of a cooling-pipe E', located,preferably, in the center of the said cooling vessel. This cooling-pipeE' is carried through the cover of the vesselll and the warmer ice-waterruns away at the top of the said pipe E through a pipe e into areservoir F for collecting the melted ice-water, which reservoir isplaced outside the ice-chest A, Fig. 2, in order to allow of its beingmore easily emptied. lf the cup E be also filled with ice, a still morerapid cooling action will be produced by the cooling-pipe E.

The beer-cooler II, which is kept hermetically closed by means of acover lI, held down by hinge-bolts and wing-nuts 71 is arranged in thefront lower buffet or counter-like part of the ice-chestA. As thislowerfront part is separated from the higher rear part of the icechest by apartition D, which does not quite extend to the floor of the ice-chest,the heavier cold air must emerge below between the partition D and thebottom f the ice-chest and flow around the outside ofthe cooling vesselH. The warmer air rises up to the cover A2 of the buffet part of theice-chest, the stepped part A of which is sloped upward or inclined at dunderneath toward the front wall of the ice-chest with the object ofdeflecting, facilitating the escape of the rising air from the buifetinto the upper part of the ieechest.

A small chamber K, Fig. 7, provided with a float-valve 7c3 and let-offcock 7o, is mounted on a pipe 7a2 on the beer-cooler II in the coolchamber of the buffet and may be connected by means of a tap k' and pipeL with the usual drawing-off apparatus g g' of a cask G, the beer from.which is to be conveyed into the cooler. The cask G is also connectedwith a carbonio-acid containerJor with an air-pump by means of the tap gand pipe J', so that by the pressure of the carbonic acid (or of airpumped into the cask) the beer may be transferred from the cask directlyinto the cooler without its being necessary to open any door or the likeon the ice-holder.

In order to prevent any frothing up of the beer in its transference fromthe cask to the cooler, a pipe 'm2 is located above on the cover of thecooler, which pipe is carried through the buffet-top and has at the'upper end a small chamber M, Fig. 7, in the bottom of which a metalball-valve m is located, which closes the mouth of the pipe m2. Theescape of air from the cooler ll on the entrance of the beer therein isthus rendered more diilicult, as the valve must be lifted before the aircan escape, or, in other words, a counterpressure tothe too-rapidentrance of the beer is created.

At the top of the small chamber M an india-rubber float-valve m', heldin a loop-piece or stirrup, is provided, which closes the chamber assoon as it is filled with beer. Froth or the like may escape at the topof the chamber M after the opening of the tap m3 by means of a pipe 19into a vessel placed beneath. The chamber M may be emptied and cleanedthrough a tap m4, located on the bottom.

The beer is withdrawn from the cooler by means of a tap O and pipe o,while the beerdrip falls from a dish F2 into the funnel fof a pipe F',and from the latter is conveyed direet into the vessel F for catchingthe water arising from the melting of the ice.

rlhe advantage of this improved ice-chest or refrigerator withsupply-buffet and separate cooler consists, essentially, in the beerbeing always well and eq'ually cooled, and the beer can be kept for along time without deteriorating in quality. beer from the cask into thecooler is eilected in a simpler and more rapid manner without frothingand without necessitating the opening of the ice-chest. The consumptionof ice is very small, while the cooling is most eifectivc.

`A draw-oil? tap or plug a is located on the front of the bottom of thechest, which bottom also slopes toward the front to allow of the wastewater being run off and to facilitate the cleaning.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. In an apparatus for cooling and dispensing beveragesthe combination with the sideboard substantially as set forth, theice-con taining vessel located in the upper smaller part of thesideboard, the beverage-containing vessel located in the lower largerpart of the sideboard, of a second receptacle for ice located on top ofsaid beverage-cooling vessel, means for conveying the water from themelting ice in the said upper ice-container to said latterice-container, and means for passing the water from the melting ice insaid latter ice-container through the said beveragecontaining vessel andthen out of the sideboard, substantially as set forth.

2. In an apparatus for cooling and dispensing beverages the combinationwith the sideboard substantially as set forth, ot an icecontainingvessel located in the upper smaller part of the sideboard, thebeverage-containing vessel located in the lower larger part of Thetransfer of the the sideboard, a U-shaped Vessel extending downwardlyinto said beverage -containing vessel, a second receptacle for icelocated on top of said beverage-containing vessel, means for conveyingthe water from the melting ice in said upper ice-container to saidlatter icecontainer, and means for passing the water of melting fromsaid latter ice container through said U-shaped Vessel, and then out ofthe sideboard, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

WILHELM BACHNER.
